Product details
Overview
LTC6930IDCB-8.19#TRMPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator delivering factory-programmed 8.192MHz master frequency with user-selectable divide-by-1 to 128 outputs (64kHz to 8.192MHz), ±0.1% max frequency accuracy over –40°C to 85°C, 105µA typical supply current at 32kHz/3V, and <110µs start-up time. It serves as a precision timing source in battery-powered microcontroller systems requiring stable low-power clocking.
For engineers reviewing the LTC6930IDCB-8.19#TRMPBF datasheet, LTC6930IDCB-8.19#TRMPBF pinout, LTC6930IDCB-8.19#TRMPBF application, or LTC6930IDCB-8.19#TRMPBF equivalent, key selection factors include its 8-pin DFN package, DIVA/DIVB/DIVC digital frequency control interface, 1.7V–5.5V single-supply operation, RMS period jitter <0.8ps at 8.192MHz, and guaranteed performance across industrial temperature range.
Technical Context
The LTC6930IDCB-8.19#TRMPBF integrates a proprietary switched-capacitor-controlled master oscillator (factory-set to 8.192MHz) with a binary divider chain (N = 1–128) and CMOS output driver. Its internal regulation minimizes supply-induced frequency drift (0.07%/V) and temperature-induced drift (0.001%/°C for DFN package).
Frequency selection is implemented via three CMOS-compatible digital inputs (DIVA, DIVB, DIVC) that configure the divider ratio without external components. The device holds OUT low during power-up and transitions cleanly on DIV pin changes-no runt pulses or glitches occur, enabling dynamic reconfiguration in real-time embedded systems.
Key Specifications

FAQ
What is the maximum output frequency of the LTC6930IDCB-8.19#TRMPBF and how is it selected?
The LTC6930IDCB-8.19#TRMPBF has a maximum output frequency of 8.192MHz, achieved when DIVA = DIVB = DIVC = 0 (divide-by-1 mode). This frequency is factory-programmed as the master oscillator frequency. The device supports eight discrete output frequencies from 64kHz to 8.192MHz via binary configuration of the three DIV pins, as defined in Table 1 of the datasheet. No external components or programming interface are required.
Does the LTC6930IDCB-8.19#TRMPBF require external load capacitors like quartz crystals?
No, the LTC6930IDCB-8.19#TRMPBF does not require external load capacitors. It is a fully integrated silicon oscillator with an on-chip resonator and regulated oscillator core. Only standard 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are required for stable operation. This eliminates the need for crystal load matching and reduces layout sensitivity.
What is the guaranteed operating temperature range for the LTC6930IDCB-8.19#TRMPBF?
The LTC6930IDCB-8.19#TRMPBF is rated for operation from –40°C to +85°C (I-grade). This specification is fully tested and guaranteed across the entire range, unlike C-grade variants which are only characterized from 0°C to 70°C. The DFN package exhibits 0.001%/°C frequency drift over this range, supporting reliable timing in industrial environments.
Can the LTC6930IDCB-8.19#TRMPBF be used with a 1.8V supply voltage?
Yes, the LTC6930IDCB-8.19#TRMPBF operates over a supply range of 1.7V to 5.5V, fully including 1.8V. At 1.8V and 8.192MHz output (DIV=1), the typical supply current is 210µA. Frequency accuracy remains within ±0.45% over temperature, and output rise/fall times increase slightly to ~3.5ns - still compatible with standard CMOS logic interfaces.
How does the LTC6930IDCB-8.19#TRMPBF handle switching between different DIV settings during operation?
The LTC6930IDCB-8.19#TRMPBF switches cleanly between DIV settings with no glitches, runt pulses, or frequency transients. The output transitions to the new frequency within one complete cycle of the *new* output frequency. For example, changing from 8.192MHz to 4.096MHz takes ≤122ns. This behavior is enabled by synchronous internal divider architecture and is verified across all voltage and temperature conditions.
